Abstract

The mirror is mounted on a part spherical member whose centre lies on the mirror surface, and the spherical member is borne by a ball socket. For mirror adjustment the spherical member is pref. attached to a lever which passes through the base of the socket and is pref. held by a spring against the adjustable point of intersection of two movable stops. Pref. the stops are fitted with wheels that roll on the outer edges of a rectangular frame. Adjustments are made usually in the Cartesian (x, y) co-ordinate system, but may use polar co-ordinates.

Description

Lager für einen schwenkbaren SpiegelStorage for a swivel mirror

Die Erfindung betrifft ein Lager für einen in zwei Richtungen schwenkbaren Spiegel.The invention relates to a bearing for a mirror that can be pivoted in two directions.

Für kohärentoptische Systeme besteht ein Bedarf an Lagerungen für Spiegel, welche in einem möglichst grosseh Raumwinkelbereich präzise und trotzdem schnell und leicht verstellbar sind.For coherent optical systems there is a need for bearings for mirrors which can be adjusted precisely and nevertheless quickly and easily in the largest possible solid angle range are.

Es ist das Ziel der Erfindung, eine derartige Lagerung zu schaffen, welche ein Verstellen sowohl durch Steuerung nach Polar- als auch in cartesisehen Koordinaten als auch nach beliebigen anderen zweidimensionalen Koordinatensystemen gestattet.It is the aim of the invention to provide such a storage create which an adjustment both by control according to polar as well as in Cartesian coordinates as well as according to any other two-dimensional coordinate system is permitted.

Erfindungsgemäss wird dies dadurch erreicht, dass der Spiegel auf der Kreisfläche eines Kugelabschnittes angeordnet ist, wobei das Zentrum der Kugel auf der Spiegeloberfläche liegt, und dass der Kugelabschnitt in einer Kugelpfanne entsprechenden Durchmessers gelagert ist.According to the invention, this is achieved in that the mirror is arranged on the circular surface of a segment of a sphere, with the center of the sphere lying on the mirror surface, and that the ball section corresponds to a ball socket Diameter is stored.

Zur Bewegung und Steuerung ist der Kugelabschnitt mit einem hebelförmigen, radial zur Kugel angeordneten Fortsatz versehen. Dabei ist der !Portsatz mittels einer in einer zur Ebene der !Nullstellung des Spiegels parallelen Ebene wirksamen Verstelleinrichtung bewegbar.For movement and control, the ball section is equipped with a lever-shaped extension arranged radially to the ball. The! Port set is in a to Level of the zero position of the mirror parallel plane effective adjustment device movable.

Durch diese Bauweise ist der Spiegel mittels des !Fortsatzes direkt in Polarkoordinaten schwenkbar.Due to this construction, the mirror can be swiveled directly in polar coordinates by means of the extension.

Zur Steuerung nach cartesischen Koordinaten ist gemäss der Erfindung der Fortsatz mittels einer Feder gegen den zweidimensional verschiebbaren Kreuzungspunkt zweier in einer Ebene ge eindimensional verschiebbarer, gekreuzter Anschläge gehalten. Dabei sind.vorteilhaft die Anschläge mittels EoILen auf der Aussenkante eines rechtwinkligen, mit der Kugelpfanne starr verbundenen Rahmens geführt.To control according to Cartesian coordinates, according to the Invention of the extension by means of a spring against the two-dimensional displaceable crossing point of two ge one-dimensionally displaceable, crossed stops held. The stops by means of EoILs on the outer edge of a right-angled with the Ball socket out rigidly connected frame.

Zur Steuerung nach beliebigen Koordinaten sind die Anschläge, an denen der Fortsatz anliegt, entsprechend gekrümmt.For control according to any coordinates, the stops on which the extension rests are correspondingly curved.

Das Lager besteht aus einem Block 1 mit einer ausgesparten Kugelpfanne 2, welche nach zwei Seiten offen ist und einem darin gelagerten Kugelabschnitt 3, an dem ein Oberflächenspiegel 4 befestigt ist. Der Drehpunkt D liegt auf der Oberfläche des Spiegels und zwar vorzugsweise in der Mitte von dessen Oberfläche.The camp consists of a block 1 with a recessed Ball socket 2, which is open on two sides and a ball section 3 mounted therein, on which a surface mirror 4 is attached. The pivot point D lies on the surface of the mirror, preferably in the middle from its surface.

Der Kugelabschnitt 3 weist einen radialen senkrecht zur Oberfläche des Spiegels gerichteten Fortsatz 5 auf, welcher durch die hintere Öffnung der Kugelpfanne herausragt. Durch diesen Fortsatz ist der Spiegel nach Polarkoordinaten direkt steuerbar.The spherical section 3 has a radial perpendicular to Surface of the mirror directed extension 5, which protrudes through the rear opening of the ball socket. By the mirror can be controlled directly according to polar coordinates.

Zur Steuerung nach cartesischen Koordinaten sind auf der Rückseite des Blockes 1 zwei gerade Anschläge 5 und 6 vorgesehen, welche mittels Rollen R auf einem rechtwinkligen Rahmen 8, der mit dem Block 1 starr verbunden ist, verschiebbar gelagert sind.To control according to Cartesian coordinates, two straight stops 5 and 6 are provided on the back of the block 1, which by means of rollers R on a right-angled frame 8, which is rigidly connected to the block 1, displaceable are stored.

Der Fortsatz 5 wird mittels einer Zugfeder 9 gegen den Kreuzungspunkt der Anschläge 5 und 6 gehalten. Durch voneinander unabhängiges lineares Verschieben der Anschläge 6 und 7 ist der Spiegel 4- in zwei zueinander senkrechten Richtungen x, y schwenkbar.The extension 5 is by means of a tension spring 9 against the Crossing point of stops 5 and 6 held. Through each other independent linear displacement of the stops 6 and 7 is the mirror 4- in two mutually perpendicular Can be pivoted in directions x, y.
